Lua/SWIG wrap userdata from within Lua?

The very definition of userdata is that Lua does not, can not, and doesn't want to know what it is. It's your data- what it is is your problem. If you want to manipulate it, then you must call C functions with it (operator overloads available by metatable setting).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
